Median Orbit Repeatability (see table below): 11.0 cm

We continue to exclude data from IGS stations that do not employ Dorne-Margolin
style antennae (see IGS Report #6260).

A large clock discontinuity (reset) of about 42 microseconds was detected
for PRN14 at approximately 02:05 on day 026.  Additionally, it appears that
the drift of the clock onboard this satellite simultaneously experienced a
shift from about -2 ps/s to +67 ps/s.

Due to potential problems, data from stations mentioned below were not
considered for use in the global solution for the day indicated.  (For
geographical reasons, they may not have been used in any case.)

WARNING: ALGO (not USNO) used as reference clock days 023-025, 028, and 029.
WARNING: FAIR (not USNO) used as reference clock day 027.
WARNING: Data from PRN11 and PRN15 excluded the entire GPS week 1046.
WARNING: Data from ALIC, AUCK, BRUS, CAS1, CEDU, CHAT, DARW, GOL2, HOB2, KOSG,         MAC1, NANO, NOUM, RIOG, STR1, THTI, TID2, TOW2, USNA, YAR1, YSSK, PRN18,        PRN26, PRN31 excluded day 023.
WARNING: Data from BRAN, FORT, GOL2, IISC, KELY, LHAS, TID2, USNO, YSSK, PRN18,          excluded day 024.
WARNING: Data from BRAN, KELY, ONSA, TID2, TSKB, YSSK, PRN18 excluded day 025.
WARNING: Data from BRAN, GODE, HOLP, TID2, YSSK excluded day 026.
WARNING: Data from CASA, DARW, GODE, GOL2, HOLP, TID2, PRN18 excluded day 027.
WARNING: Data from DARW, GOL2, HOLP, REYK, TID2, PRN01, PRN18 excluded day 028.
WARNING: Data from DARW, GOL2, KARR, KELY, MAC1, NICO, TID2, PRN10, PRN18                excluded day 029.

In the following table, UT1R-UTC are the integrated values based on estimated
